Description

Technical Field

[0001] The utility model belongs to the technical field of punching machines, and specifically relates to an automatic and rapid punching machine for fence boards. Background Art

[0002] A punching machine is used for sheet metal processing, stamping, molding, embossing and other activities that force metal into the moving part of a die, including:

[0003] A folding CNC punching machine is suitable for punching processing of leather, cowhide, artificial leather, plastic, PU, EVA, PVC, various fabrics, papers, leather accessories, shoe uppers, decorative pieces, curtains, automotive leather seats, etc., and is widely used in industries such as automotive parts (breathable seat cushions), luggage and handbags, stationery, shoes, breathable materials, advertising papers, etc.

[0004] A folding mechanical punching machine is mainly suitable for large-area punching processing of sponge, leather, cardboard, non-woven fabric, etc.

[0005] A folding pneumatic punching machine, also known as a pneumatic punching machine and a plastic bag punching tool, is a pneumatic punching die auxiliary to a bag-making machine. It is a pneumatic die that receives signals from the computer of the bag-making machine and transmits them to the solenoid valve for operation. Its structure is similar to a cold punching die and is mainly used for punching plastic bags and papers. Technical verification: The die bases of pneumatic punching machine products are all made of precision-cast alloy materials, the stamping power is selected from high-precision cylinders, and the punch heads are selected from imported die steel (ASP-60). The structure meets the requirements of stamping, with beautiful appearance, high action frequency, strong wear resistance, long service life, and a maximum frequency of up to 320 times.

[0006] A folding hydraulic punching machine is suitable for punching L-shaped and H-shaped flat steels, copper bars and aluminum bars. It is designed with a flat base at the bottom and is stable and not easy to fall over. It has a single-hole oil return, and the die is made of high-carbon tungsten alloy steel and is not easy to break. In particular, the CH-60 and CH-70 split-type hydraulic punching machines are specially used for punching metal plates such as angle iron, flat iron, and copper plates, and are especially suitable for field operation in industries such as electric power and construction.

[0007] In the current actual application process, wood-plastic boards are mostly punched by hydraulic punching machines, especially fence boards. However, the structures of existing hydraulic punching machines are mostly unstable, and it is easy to have deviations during the punching process of fence boards, and it is also easy to cause cracking of the boards around the punched parts.

The upper ends of the two brackets 1 are connected by a hydraulic cylinder support 2. A hydraulic cylinder 3 is provided on the hydraulic cylinder support 2. A hydraulic cylinder connecting plate 4 is provided below the hydraulic cylinder support 2. Below the hydraulic cylinder connecting plate 4, a punching upper connecting plate 5, a punch mounting plate 6 and a punching guide die 7 are sequentially provided;

[0040] A number of punches 61 are provided on the punch mounting plate 6. A stripping plate 62 is provided below the number of punches 61. The stripping plate 62 is slidably and limitedly connected to the punch mounting plate 6 through slide pins 63 on both sides thereof. Springs 64 are provided on the slide pins 63;

[0041] The stamping guiding die 7 includes a die bottom plate 71. Above the die bottom plate 71, there is an L-shaped guiding plate 72. Guide through slots corresponding to the punch 61 are provided in both the horizontal section of the stripping plate 62 and the guiding plate 72.

[0042] In a possible implementation manner, the stripping plate 62 is arranged below the horizontal section of the guiding plate 72.

[0043] In a possible implementation manner, the bracket 1 is fixed on the workbench 01. The stamping guiding die 7 is arranged on the workbench 01, and the stamping guiding die 7 is also provided with a stamping guiding die pressing plate 9.

[0044] In a possible implementation manner, guiding shafts 65 are provided at both rear ends of the punch mounting plate 6. The lower ends of the guiding shafts 65 are connected to the stamping guiding die pressing plate 9.

[0045] In a possible implementation manner, a groove is provided on the die bottom plate 71. A stamping lower die plate 8 is arranged in the groove. Stamping holes corresponding to the punch 61 are provided in both the stamping lower die plate 8 and the bottom of the groove.

[0046] In a possible implementation manner, the output end of the hydraulic cylinder 3 passes through the hydraulic cylinder support 2 and is connected to the hydraulic cylinder connecting plate 4.

[0047] In a possible implementation manner, as Figure 6 shown, during the use process, the automatic punching machine is arranged on the workbench 01 and automatically feeds materials through the conveyor belt 02. A servo clamping device is also provided on the workbench 01. There is an induction baffle when the fence plate moves into place. After the induction baffle senses the fence plate, the servo clamping device acts, and at the same time, the induction baffle rises. The fence plate runs to the processing station driven by the servo clamping device.

[0048] A stamping lower die plate is arranged below the fence plate. The upper part of the automatic punching machine automatically presses on the fence plate to clamp the fence plate tightly. The punch 61 automatically punches holes through the guide cylinder. Then, after the punch 61 retracts, the lower stripping plate 62 of the automatic punching machine rises with the automatic punching machine and loosens the fence plate (through the spring 64); Using the automatic punching machine, the production efficiency is higher compared with drilling.

[0049] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
